IMPROVEMENT IN PASSENGER-REGISTERS.

Specification forming part of Letters Patent No. 183,410, dated October17, 1876 application filed August 28, 1876.

To all whom it may concern Be it known that I, WILLIAM MEHAN, ofHoboken, in the county of Hudson and State of New Jersey, have inventeda new and'Improved Passenger-Register, of which the following is aspecification:

Figure l is a plan view. Fig. 2 is a side elevation, in part section, online a: w in Fig. 1.

My invention consists in the arrangement of a cam and friction-rollerwith a turnstile and movable platform, so constructed that the personpassing the turnstile must step upon the movable platform, by the motionof Which, under control of the cam, the apparatus is made to registeronce, and cannot be made to do more or less.

A is a turnstile, placed in the passage through which passengers mustpass, and B is a movable platform, resting on pivots a on the levers b,which are journaled in the frame which supports the turnstile at c. Thefree ends of these levers rest upon the shorter ends of the levers d e.The lever dis pivoted at d, and is provided with a friction-roller, f,at its longer end. The lever e is pivoted at g, and is connected at itsouter end with a rod, h, that works the registering apparatus. 0 is aratchet-wheel placed on the turnstile-shaft, and provided with a pawl,i, that prevents it from turning backward. A cam, D,' is attached to theturnstile-shaft immediately below the ratchet G, and is provided withfour concaved notches, into which the frictionroller f may drop, whichcorresponds with the spaces in the turnstile. Pinsj are placed centrallyin the notches in the cam, leaving sufficient space for the roller f tofollow the cam without striking the pins. E is a heavy spring, that canbe depressed only by the weight of a person upon the platform. Anysuitable registering apparatus may be connected with the rod h.

The operation of my invention is as follows: A person entering theturnstile passes over the movable platform, and in so doing depressesthe levers b b, and consequently the shorter ends of the levers d c.This causes the longer end of the lever d to rise into and follow thenotch in the cam D as the turnstile is turned. This allows the lever cto move, carrying the rod h upward and operating the registeringapparatus.

It will be seen that one passenger cannot register twice, as the pin jprevents the roller f and lever d from dropping, so that a full strokecan be made. When there is no weight on the platform B the roller frests below the pin j, and the turnstile may be turned withoutregistering. The pawl t' and ratchet O prevent the apparatus fromturning backward, so that persons going in must step on the platform,while persons passing out may go on the other side.

The top of the turnstile may be corrugated or provided with ridges orpoints, to prevent passengers from riding on it through the passage.

Having thus described my invention, what 1 claim as new, and desire tosecure by Letters Patent, is-

In combination with a turnstile, A, and ratchet O, the cam D, havingconcave notches, and the pins j centrally located in the notches, thelevers (I e and b 1), spring E, and platform B, substantially as hereinshown and described.

WILLIAM MEHAN.
